WESLEY A. PAUL, OF MOLINE, ILLINOIS, ASSIGNOR TO DEERE & COMPANY, OF

MOLI'NE, ILLINOIS, A CORPORATION OF ILLINOIS.

GANG-PLOW HITCH.

Application filed October 5, 1912.

To all whom it may concern Be it known that I, VVnsLnY A. PAUL, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Gang-Plow Hitches, of which the following is a speci fication, reference being had therein to the accompanying drawing.

My invention relates to plows, and more particularly to that class known as gangplows, comprising a plurality of plowbodies, and a frame to which they are attached.

The object of my invention is to add to the strength of the means of attachment of the plow-beams to the frame without complicating the mechanism or increasing the expense of construction.

Referring to the drawings in which similar letters indicate identical partsFigure 1 is a plan view of a gang-frame showing three plow-bodies attached thereto, a suflicient number to demonstrate my invention. rigf2 is a detail in perspective.

lhe gang-frame is preferably of metal and comprises a draft-bar 1, a side-bar 2, and a diagonal beam 3, the latter being the rear of the frame to which the plows are attached, these various parts being braced and secured together in such a manner as to present a structure of great strength and rigidity. The gang-frame 1 is supported on wheels & and 6, and a furrow-wheel 5. Preferably I construct the diagonal beam of channel-beams 7 and 8 vertically disposed with their flanges extending outwardly and horizontally, the two beams being connected by a plate 9 rigidly bolted to their upper flanges. Secured to the beam 3 is a series of plates 10, one for each plow, but to only three of which I have shown plows attached. Preferably I attach the plates 10 to the under side of the beam 3, bolting it securely to the channel beams 7 and 8, but I do not limit myself to this structure, as the plates 10 can be secured to the upper side of the beam 3.

Each plow comprises the usual landside share and moldboard secured to a beam 11. Each beam 11 is pivotally attached to a member 12, the end of which is enlarged, bored out, and threaded to engage with a screw 13 passing therethrough and having its bearings in an end of the plate 10, and

in a downwardly extending portion 14 of a plate 15 bolted to the plate 10, the screw 13 being operable to raise or lower the end of the plow-beam 11. At the opposite end of the plate 10 is a similar screw 16 engaging with a member 17, similar to the member 12, and having its bearings in the end of the plate 10, and in. a downwardly extending portion 18 of the plate 15. Abrace 19, forming a part of the plow-beam structure, is pivotally connected to themember 17 and extends rearwardly to its juncture with the plow-beam 11 where it is rigidly secured. By this construction the plowbeam structure is pivotally secured to the beam at widely separated points. A brace 20 is secured to the beam 11 and extends rearwardly at an angle thereto, its rear end being bolted to the brace 19.

In plows of this description, where single plow-beams are employed, it is essential that the construction should be such that the side thrust of the plows and the torsional strain of the plowbeams when the gang is being operated will be counteracted. I accomplish this result by the mechanism above described, and by making the width between the connection of each plow with its corresponding plate 10 greater than the width between the plow-beams; this excess of width can only be secured by arranging the plates 10 as shown with the landward end of each of the plates 10, extending landward of the furrow-end of each succeeding plate. To add to strength of the plate 10, I provide a brace 21 for each of the plates 10, one end of each brace 21 being bolted to the beam 3 and the other end to the plates 10 as shown.

I do not limit myself to the exact arrangement of parts shown as it is evident that it may be varied without departing from the spirit of my invention.

What I claim is 1. In a gang-plow, the combination with a main-frame, of a plurality of plows, landward and furrowward means to connect each plow with the main-frame, each landward connection being forward of, and between the landward and furrowward connection of the next landward adjacent plow.

2. In a gang-plow,'the combination with a main frame, of a plurality of plows, landward and furrowward means to pivotally connect each plow with the main frame,

each landward connection being forward of and between the landward and furrowward connection of the next landward adjacent plow.

In a gang-plow, the combination with a main-frame, of a plurality of plows, landward and furrowward means to connect each plow with the main-frame, said landward and furrowward connections being in a plane substantially at right angles to the line of draft, each landward connectionbeing forward of and between the landward and furrowward connection of the next landward adjacent plow.

4. In a gang-plow, the combination with a mainframe, of a plurality of plows, landward and furrowward means to connect each plow with the main-frame, the landward and furrowward connections of each plow being in a plane substantially at right angles to the line of draft, and the distance between the landward and furrowward connecting means being greater than the distance between the adjacent plows.

5. In a gang-plow, the combination with a main-frame, of a plurality of plows having their beams connected with the main-frame, abrace connected to each plow-beam and to the main-frame, the brace and beam connections of each plow being in a plane substan tially at right angles to the line of draft, and

the distance between said brace and beam connections with the main-frame being greater than the distance between any two adjacent plows.

6. In a gang-plow, the combination with a main-frame, of a plurality of plows having their beams connected with the main-frame, a brace connected to each plow and the mainframe, the distance between said brace and beam connections with the mainframe being greater than the distance between any two adjacent plows.

7. In a gang-plow, the combination with a main-frame, of a plurality of plows having their beams connected with the main-frame, a brace connected to each plow-beam and to the main-frame, the brace connection of each plow with the main-frame being located forward of and between the brace and beam connection of the next landward adjacent plow to the main-frame.

8. In a gang-plow, the combination with a main-frame, of a plurality of plows having their beams pivotally connected with the main-frame, braces connected to said plows and pivotally connected to the main-frame, the brace connection of each plow with the main-frame being located forward of and between the brace and beam connection of the next landward adjacent plow to the mainframe.

9. In a gang-plow, the combination with a main-frame including a diagonal beam, a plurality of plows connected to one side of said; beam, and a brace secured to the beam of each plow and connected to the opposite side of said diagonal beam, said brace and plow connections to the main-frame being in a line substantially at right angles to the line of draft, the distance between the connection of the plow-beam and the brace of each plow to the diagonal beam being greater than the width between any two adjacent plows.

10. In a gang-plow, the combination with a main-frame including a diagonal beam, a plurality of plows connected to one side of said beam, and a brace secured to the beam of each plow and connected to the opposite side of said diagonal beam, the connection of the beam and brace of each plow to the diagonal beam being in a line substantially at right angles to the line of draft, and the distance between the connection of the plowbeam and the brace of each plow to the diagonal beam being greater than the width between any two adjacent plows.

11. In a gang-plow, the combination with a main-frame, including a diagonal beam, a plurality of plates secured to said beam, a plow-beam connected to one end of each of said plates and a brace secured to eaclnplpwbeam and connected to the opposite end or each plate, the width between the connection of each plow-beam and brace being greater than the width between any two adjacent plows.

12. In a gang-plow, the combination with a main-frame including a diagonal beam, a plurality of plates secured to said beam and projecting beyond both sides thereof, a plowbeam connected to one end of each plate, a brace secured to each plow-beam and connected to the opposite end of each plate, the connections of each plow-beam and brace to its respective plate being in a line substantially at right angles to the line of draft, and the width between the connections of each plow-beam and brace to its respective plate being greater than the width between any two adjacent plows.

In testimony whereof I affix my signature, in presence of two witnesses.
